Solve the equation for y;
\n" ); document.write( "adjust into slope intercept form;
\n" ); document.write( "form the general slope-intercept form equation and solve for b.
\n" ); document.write( "Substitute point P and new slope of \"-%281%2Fm%29\" into this formula for b and compute b.
\n" ); document.write( "Replace the needed slope and value of b into the general slope-intercept equation to express your desired linear equation.\r

\n" ); document.write( "A Reminder: y=mx+b is slope-intercept form for a line. A line perpendicular to it will need a slope of \"-%281%2Fm%29\".\r
